# (4/4) Straight-line Check

* Move the robot straight, and echo the `/odom` topic.
* Align the wheels accordingly to test straight linear movement. It’s recommended to draw lines on the floor for accuracy.
* Give only linear speed. Check the robot is travelling straight. A slight deviation is acceptable (1 - 2 degrees), but no more than 5 degrees.
